Description:Measuring |Np and |Pu in urine at low levels is important for both biomonitoring and radiological emergency response. Here we report a newly developed and validated analytical method used to determine |Np and |Pu in urine by selective retention of Np and Pu from 2mL of urine directly onto TEVA® resin followed by SF-ICP-MS (coupled to a membrane desolvating introduction system) detection. The method provides solid phase extraction of Np/Pu with observed recovery ratios ranging from 89% to 113% and rapid results with limits of detection well below recommended detection guidelines for children and pregnant women (NCRP 161 reference).
